I have read the books, watched the shows and personally have met and worked with autistic people but I can not say she "nailed" the depiction of a person with Asperger's. I can say, howerver, that she nailed it for me and in my opinion it is perfect. She did a exceptionally good job of being a male in King's Affection but in this one she could not be more impressive. Perhaps, she is scripted on how to act but she does it perfect. The show is a relatively solid 8/10 with the same scripts, storyline and great actors but Park Eun-bin genius is what makes this amazing. Again, my opinion but Korean actors are just better overall but she is another level.
